The three limit sliders 18 are respectively slidably arranged on the three guide rods 27. The bottom of the inner cavity is buckled with a bottom cover 15, and a small hole for the electrode wire 5 to pass through is opened at the center of the bottom cover 15.
[0021] Through the structures such as the rotating disk 8 and the clamping block 14, the electrode wire 5 bypasses the wire guide wheel 4, passes through the wire entry hole 6 and finally passes out through the wire outlet hole 7. The three sliding shafts 24 can be driven to slide along the arc-shaped limit groove 11 by rotating the rotating disk 8. At the same time, the moving direction of the limit slider 18 is limited by the guide rod 27, so that the sliding shaft 24 can drive the limit slider 18 to move axially along the guide rod 27, thereby driving the three clamping blocks 14 to approach or move away from each other, so as to achieve the purpose of stably clamping and fixing the electrode wires 5 of different thicknesses, thereby improving the adaptability of the device, and through the detachable bottom cover 15, the internal structure can be easily disassembled and repaired, and it is also convenient to pass the electrode wire 5 out of the wire entry hole 6.
